Hi Rup,

Thank you for contacting the Microsoft Community.

I understand how important and time-sensitive it is to have Visual Studio installed, especially when you're ready to move forward but are facing this kind of roadblock. Your request is important, and I’ll make sure it reaches the team best positioned to support you.

You’ve taken all the right steps so far, and I appreciate the effort you've made in trying to resolve this issue on your own. The error code 0x80070643 often points to deeper system-level conflicts that can’t always be resolved through basic troubleshooting alone.

While our core support focuses on exam registration and Microsoft Credentials, I’m happy to share some next-step guidance based on similar cases I’ve encountered. In those instances, the most effective resolution came through direct coordination with the Visual Studio Subscription support team. They specialize in resolving installation and activation issues and are best equipped with the tools and insight needed to help get you up and running successfully.

They will be creating a separate case with a different reference ID and assist you from here. Please refer to the link/s below for the contact information. Kindly select Visual Studio Sales, Account, Subscription and Billing Support and your Country.
